Be it'ltnown that L'CURTIS J. Bornanunr., a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Roll Protector, of which the following is a specification.

My invention relates to aV class' of devices generally employed to enclose the openvends of cylindric rolls of rooting paper or other fabrics, the interiors of which rolls are left intentionally hollow to contain, in the instance of roofing material, packages of cement and nails suoli as are used'in laying the rooting material, and in the case et other fabricsgarticles which may be used with such fabrics.

The inclosing devices, as such, to the application and use of which my invention is intended, are end-caps one of which is adapted to be placed on each end of the roll of the Wrapped material, and which are united and lheld in place by a connecting rod, for the purpose of protecting the ends of the rolland retaining the contents of the hollow interior of the roll from falling out.

As heretofore made, these end-caps have, as stated, been adapted to be held together upon the roll by a rod which has been passed through the hollow interior of the roll and both of the caps, and has been connected with one ofthe caps by a hooked. shape bend and with the other by a nut threaded upon that part of the rod. which extends beyond such cap, l

In the application of the bent end of the rod it has been usual to form a hole through the center of a cap and another hole near the periphery of said cap,-the cap itself being preferably cup-shaped, that is to say, formed with a flat central bottom through which the holes are made, which Vflares outwardly in the form of wallsthe outer edges of which are flattened to correspond with the plans of the bottoni of the cap so as to forni a circumferential flange which, in the application of the cap, lies upon the end of the wrapped material to enclose its hol- In the foregoing construction, the hooked end Of the rod which'is entered and passes through the holes in one of the bottomsfis liable, when the strain of the nut is, througl the rod, put upon the bottom mentioned, to bend it inward between the holes, some.-

' times with the result of breaking through through the roll and clamp the caps together, the object, of my inventionV is to so construct the rod that while it lcannot injure the cap to which its hooked end is applied, itv will hold the two caps firmly together under t-ension which prevents the separation of the caps, loosening of the nuts and loss of caps and mclrages, and, at the same time, hold them tightly clamped toward cach other tov enclose the ends f the roll without injuriously affecting` either cap. lt will also permit of the use of a lighter and cheaper rod.

It will further in the transportation or handling` of the device obviate the .tendency` of the inner end of the hook heretofore used,-which end passes through a hole cen'- tral of the bottom of the lower ycap,to puncture, for instance, the bag orcan 1containing` the cement, so as to let it escape, and will otherwise prevent injury to the contents vof the interior of the roll.

lVith the object of overcoming the fore,- going, and other, disadvantages of the p r tectors heretofore used, I have'invented a protector which comprehends tWo end-caps and a connecting rod,Y one end Of which, 111 practice the lower end has an Yextended bearing portion and is preferably shaped in the general ,form of a loopthe members of which may havev any desire'd'contour, and for purposev of killustration only they are shown as occupyingv an angle with respect tothe rod and to the plane of the bottom ofthe cap, until the nut which I apply as heretOfore to the .Qther Vend/of the rod, 1S Screwed down upon the other, in practice the upper-cap, so as to exert such'tension upon the rod as-will result in the-positive dranf'ing of the caps together,-the loop acting as a spring u'pon the Arod-to retain a tension upon the nut and no dependence being, as heretofore, placed upon the strength of the metal of the lower cap between its apertures to resist the pull of the rod upon both. caps when the nut is turned and the tendencyto bend or break through the bottom of the lower cap,

The tie rod is bent to. pass through the central hole of the uppercap, and is provided, as heretofore, with a nut to exert the usual tension or pull upon the rod. y

The formation of the bearing portion of the tie rod is not of the essence of the invention, but I prefer to adopt such form that a substantial bearing area is provided.

In the accompanying drawings I have illustrated a preferred embodiment of my invention in which Figure 1 represents a perspective of a roll protector illustrating the upper inclosing cap in place.

Figure 2 represents a central,- vertical section through a roll Villustrating the` ap pliflzation of both caps and my connecting ro Figure 3 represents a bottom plan of the lower cap removed from the roll, illustrating' in dotted lines the loop of the rod vin place, andthe cap being ofcircular formation.

Figure L represents a plan view of an-' other embodiment of a cap which can be employed where a full cap is not needed,

therebyV effecting a saving of metal.

Figure 5 represents a plan of two caps as seen in Figure 4, each of elliptical out-V line and disposed, referably to the roll, at right angles to each other to provide additional reinforcen'ient and also substantially a circular contour. i *Y Figure 6 represents anelevation of my rod removed from the caps and roll, and illustratingthe form of my loop in the nor- I mally angular position of its members before the tension of the nut is exerted upon it.

Figure? represents a fragmentary view, similar to that of Figure 6, except that the members of the loop are shown flattened or in the position into which they are drawn by the nut when tightened.

Similar-numerals of reference indicate corresponding parts. y

InV the drawings, l designates a roll of roofing, flooring orother material, wrapped into hollow cylindric; form, and 2 an inclosing band to retain the roll wrapped, which may be of metal or other usual material, `and which may be dispensed with. A roll of roofingmaterial is usually wrapped with paper and turned in at the ends before the roll .protector is applied.

3 represents the flat bottoms, 4 the* side walls, and 5 the outwardly-extending flanges, of the end caps or roll protectors proper considered each as an entirety.

6 designates the tie rod, the upper end of which is threaded as at 7, and the lower end of which is bent outwardly and, in the form illustrated, so as to forma loop 8, the members of which in their normal positions ,are inclined at a relatively acute angle to the rod, as shown in Figure 6, and which, when the tension of the nut 9 is exerted upon them, assume a relatively flat position, or one in which all three members considered as a whole, occupy a plane in substantial parallelism with the plane of the bottom of the lower cap. The free end of the rod is deflected against or around the juxtaposed member.

X10 designates a Vcentral hole in the upper cap `through which the upper end of the connecting rod passes, as shown in Figure 2.

.11 designates a peripherally Vdisposed hole in the lower cap"throngh which the lower end of the rod above the loop passes. Y

A12 designatesa hollow center of the roll. If desired, insteadof making the protector caps kwith a circular flange, I can cheapen the construction and still provide the necessary strength by forming the cap from a strip of material in such a mannerthat when finished it will have an inwardly de ected central portion which is preferably y circular, as seen in Figures 4 and 5, and with outwardly extending oppositelysdisposed flanges which may have any ydesired formatiom, and in the majority of cases would preferably be' curved at their,y outer ends. A cap of this kind can be used to` advantage in many cases and with less `expense than is involved in the use of a cup such seen in Figure 3. Furthermore, if it is desired to useA a stronger cap, two `of, these `caps can be employed, one nested within. the other, and if they are arranged with their flanges at substantially right a11 gleskto each other a substantially circujlar contour at the peripheral edge will be pro-` vided having apertures 10 and 11, and when two cap sections are assembled in y this manner for the purpose of additional reinforcement, their corresponding aperturesI register with each other and thus provide for passing the tie rod through them. y y

, Special attention is directed to the novel Y construction and arrangeinentof the tension device havingthebearing portion which bears against or engages one cap and is disposed at an acute angle to the longitudinal axis of the body portion ofthe tie rod, since, when assembled and the nut is tightened, a tension is placed on the nut which securely holds it in position on the threaded end ofthe tie rod, so` that `the likelihood of the nut becoming loosened due to vibration in transit or the disengagement of the caps from the roll, or the `loss of the packages therein is eliminated. V Y,

A package of cementand one of nails which is to go with the roll and which is to illustrated a preferred embodiment of my invention, such embodiment is susceptible to modification particularly in the form of the various components and in otherl obvious particulars, Without departing from the spirit or scope of the invention or sacrificin any of its advantages.

{aving thus described my invention, what I claim and desire to secure b-y Letters Patent is l. A tie rod for roll protectors, comprising,` a tie rod threaded at one end and provided With a body portion, and having at its opposite end an extended bearing area oit greater Width than the diameter of the rod and disposed at an acute angle to the longitudinal axis of the body portion of the rod, said bearing area extending substantially around the central portion or the end cap of the roll protector with which it is adapted to co-operate.

2. ln a roll protector, the combination with apertnred end caps, of a tie rod to pass through cap apertures, having one end threaded, and having at its opposite end an extended bearing surface of greater Width than the diameter of the rod and disposed at an acute angle to the axis of the tie rod to form a tension device adapted to bear against one of said caps, and a nut engaging the threaded portion of said tie rod and bearing against the other of said caps, said tension device preventing the loosening of said nut.

3. In a roll protector, the combination with the apertured end caps, of a tie rod to pass through said caps, having one end threaded and having its opposite end deflected laterally to form a laterally extending loop disposed at an acute angle to the body portion of the tie rod to form a tension member having a bearing area against a juxtaposed cap, Which surrounds the central portion of said juxtaposed cap, and a nut for said threaded end to engage the other of said caps, said tension member serving to prevent the loosening of said nut and thus preventing the end caps from becoming disengaged from the roll.
